CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No.482,956, dated September20, 1892. Application filed May 16, 1892. Serial No. 438,250. (Nomodel.)

To all whom it may concern.-

Be it known that I, BENJAMIN F. WRIGHT, a citizen of the United States,and a resident of Hartwelh'in the county of Hamilton and State of Ohio,have invented certain new and usefulImprovementsin Cash-Registers, ofwhich the following is a specification.

The object of my invention is to provide a simple and inexpensive devicefor the use of retail-dealers for the purpose of accurately registeringthe amount of cash received from sales and exposing to the purchaser orothers present when the sale is made the amount of the purchase, inorder that a check may be kept of each sale made and the aggregateamount of the sales registered for any given time.

The invention consists in the peculiar combination and arrangement ofthe parts illustrated in the accompanying drawings, in connection withwhich the invention will be first fully described, and then particularlyreferred to and pointed out in the claims.

Referring to the drawings, in which like parts are indicated by similarreference-letters wherever they occur throughout the various views,Figurel is a perspective view of the device with one of the blindsthrown down. Fig. 2 is a longitudinal vertical sectional view takenalongside of the register through line at a: of Fig. 3, part of one ofthe registerwheels being shown broken away. Fig. 3 is a plan view ofpart of the case with top of the case removed and a part of the rim ofthe units-registering wheel broken away. Fig. 4 is a side elevation,upon an enlarged scale, of the pivoted shutter, the pawl which engagesthe register, and the lever for closing the shutter over the number.Fig. 5 is a detail plan view, upon an enlarged scale, of theregister-wheel.

The lower part of the case A is provided with a cash-drawer A, and theupper part has a hinged door A covering the registerwheels. The coverhas openings at over the wheels, which openings are closed by mica orother transparent material to expose the numbers. Within the case abovethe drawer are arranged any suitable number of registering One of theseis shown in side elevation, Fig. 2, and in plan view, Fig. 3. As all ofthese devices are alike the description of one will answer for all.

The registering devices are supported between parallel side plates B B,which are so cured to the front and rear ends of the case. 0 is aratchet-wheel, which is journaled upon a shaft or rod 0, which passesthrough the side pieces B 13'. Upon one side of the ratchetwheel is ahub c. D is a ring, which fits over the hub c, to which it is secured byrivets or screws. The ring D has a rim (1, upon the periphery of whichis painted or impressed the unit-numerals 5, 10, 15, 850., up to 100. Asmaller ratchet-wheel E is journ'aled upon a stud e, which is secured inthe side piece B. This ratchet-wheel is located within the rim d, andupon its side is secured a flanged wheel E, the rim of which is markedwith the numerals 1 to 10. A pawl e, which is journaled upon a stud inthe side B, engages the ratchet-wheel E and prevents its backwardrotation. A pin (1 projects inwardly from the rim (1 of wheel 'D, whichengages a tooth of the ratchet-wheel E at each revolution of the wheelD, and turns wheel E one-tenth of a revolution before it escapes fromthe tooth of the ratchet as the rim d is carried around.

In front of the door is a vertical plate A upon which is prominentlymarked a number corresponding to the amount of the purchase made. Assumein the present case this to be 5, as shown exposed in Fig. 1 and coveredby the shutter or plate F, as seen in Fig. 2. It is the intention tohave these numerals all covered until a sale is made; and when theamount of the sale is received the salesman draws down the shutter orplate F, as seen in Fig. 1, indicating that the amount of the purchasewas five cents. The drawingdown of the plateF turns the register done-twentieth of a revolution, and exposes through the opening a, theproper figure on the registering-rim. The opening of the drawer againreturns the shutter to the closed position.

I will now describe the means by which these ends are attained. Theplate or shutter F is fixed upon one end of an arm f, which is pivotedsome distance from its opposite end upon a rod f, which passes throughthe sides B B and through the arm. To the end of the armfis looselypivoted a pawl 0 the detent of which engages the teeth of theratchet-wheel O, and upon the same pivot-pin is hung the angle lever ortrigger G, the short arm g of which is hooked and extends under the rodf. Now it will be seen that when the arm f and plate F are thrown down,as shown in dotted line, Fig. 2, and full line, Figs. 3 and at, theratchet-wheel will be revolved one-twentieth of a revolution and thelong arm of the lever G carried back. By pulling the drawer open a rodat, extending entirely across the drawer will, as the drawer is drawnout, throw the shutter F up to the vertical position, the rod f actingas the fulcrum. While the shutters are in the vertical position the longarm of the trigger or lever G is free to be swung back and forth by therod ct, as the drawer is drawn out or closed, without affecting them.There may be any number of these registering devices desired. I haveshown in Fig. 1 five, to wit: for five, ten, fifteen, twenty, andtwenty-five cents.

I will now describe the means by which the ratchetwheels are preventedfrom being turned backward and a signal sounded every time one of theshutters is thrown down. H is a shaft which passes through all of thesides 13 B. It has securely fixed upon it pawls h opposite each of theratchet-wheels O. the ratchets by a coiled spring h, one end of which issecured in the shaft and the other in one of the sides 13 or B. Iisabelland t' a knocker, held at one end of a spring, the 0pposite end of whichis coiled around and secured to the shaft H. There need be only onesignal, for it will be seen that when any one of the ratchets O of theregister is revolved by its pawl c the shaft H will be partially turnedby the pawl h riding over the high part of the tooth, and when it snapsback the shaft will suddenly return to its normal position, and in doingso will bring the knocker down upon the bell. There are no blank spacesupon the register-wheels; but when the registers are set at thebeginning of a day, or any time after the record is taken, the highestnumber upon all of the wheels is brought to the highest position orunder the openings a in the door and shutters J J, which are pivotedupon the edges of the side pieces 13 B, closed over the highest numbersof both register-wheels. Pins j j are secured in the wheels at the topof the lowest numbers upon the tooth-numbered rims for the purpose ofswingingthe shutters J J (which, when in the closed position, are underthe openings a) around and exposing the first or lowest number upon theregisterwheels, as seen clearly in Fig. 5. The eX- posed faces of eachof the shutters F, when covering the numbers, are marked with num- Thesepawls are held against the teeth of hers corresponding with the numberscovered by them. They should be prominent enough for the salesman to seewhen near the register, but not so plainly visible as to detract fromthe prominence of the numbers exposed by throwing down any one of theshutters. At the close of the days business the amount of cash salesupon each of the register-wheels is taken separately and the sum of allfound. This amount should correspond with the amount of cash in thedrawer. By this means the number of sales of each kind and the totalnumber of all sales may be readily determined, as well as the totalamount received.

It will be seen that much of the complicated mechanism employed in theordinary cash-registers is dispensed with, and it is also obvious thatmany mere mechanical changes may be made in some of the parts, and thatsome of the features of my invention maybe used separately from others.

What I claim is- 1. In a registering device of the character described,the combination of the registeringwheels, the ratchet-wheels secured tothem, the exposed stationary number-plate, the pivoted arm carrying aplate or shutter to cover or expose the number on said plate, the rodupon which said arm is pivoted, and the pawl pivoted upon the end ofsaid arm opposite the shutter and engaging the teeth of theratchet-wheel which carries the register, whereby the register ispartially revolved by drawing down the shutter to expose the number onthe number-plate, substantially as shown and described.

2. The combination, substantially as hereinbefore set forth, of thecase, the exposed number-plate A above it, the cash-drawer in the lowerpart of the case, a rod crossing the drawer, a series ofregistering-wheels within the case, ratchet-wheels secured to saidregistering-wheels, pivoted arms carrying shutters at one end to coverthe numbers upon the number-plate when thrown up, and pawls at theopposite end to actuate the registers when the shutter is thrown down,the pawls pivoted to the shutter-arm and engaging the teeth of theregistering-wheel ratohets, the rods upon which the shutter-arms arepivoted, the angle-lever also pivoted to the shut ter-arms and havingits long arm projecting in the path of the crossbar in the drawer, andits short arm projecting under the rod upon which the shutter-arm ispivoted, whereby a registering-wheel is turned by throwing down theshutter-arm, and the shutter automatically returned to cover its numberby drawing out the drawer.

3. The combination of the ratchet-wheels, the registering-wheels securedthereto, the pivoted shutter, the number plate corresponding to thenumbers on the registerwheels, pivoted shutters to cover or expose thenumbers on said plate, pawls engaging the IIO teeth on theratchet-wheels and carried by knocker secured to the pawl-shaft to soundthe pivoted shutters to turn the ratchet and an alarm when the ratchetsare turned, sub- 10 register-wheel when the shutters are turnedstantially as shown and described.
